Description

Technical Field

[0001] This invention relates to cooling technology for electronic devices, and in particular to a liquid cooling medium dispersion device and method, and a cooling system. Background Technology

[0002] With the increasing power consumption of electronic devices, immersion liquid cooling technology has become the core development direction for heat dissipation, compared with traditional air cooling and the current mainstream plate liquid cooling solution. Immersion liquid cooling technology refers to immersing the heat-generating components in a non-volatile, low-viscosity insulating liquid cooling medium (such as nanofluid medium, mineral oil, fluorinated liquid, etc.), and transferring heat from the heat-generating components inside the electronic device to the external heat sink through forced circulation of the liquid cooling medium.

[0003] However, nanofluid media or liquid cooling media such as mineral oil and fluorinated liquids may agglomerate during circulation, resulting in a significant decrease in thermal conductivity and a sudden increase in viscosity, which seriously hinders the practical application of liquid cooling media in the field of immersion liquid cooling.

[0004] Therefore, how to effectively improve the cooling performance of liquid cooling media and ensure its performance in liquid cooling systems is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a liquid cooling medium dispersion device and method, and a cooling system, for reducing energy consumption while ensuring the cooling performance of the liquid cooling medium.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A liquid cooling medium dispersion device includes: a dispersion assembly comprising a dispersion chamber, a dispersion functional module, and a filter chamber, wherein the dispersion chamber and the filter chamber are isolated from each other, and the dispersion functional module is used to disperse the liquid cooling medium in the dispersion chamber and the filter chamber; an inlet pipe comprising a first branch and a second branch, wherein the first branch is used to supply the liquid cooling medium in the liquid storage device to flow into the immersion chamber of an electronic device, and the second branch is used to supply the liquid cooling medium in the liquid storage device to flow into the immersion chamber after passing through the dispersion chamber; an outlet pipe for supplying the liquid cooling medium in the immersion chamber to flow back to the liquid storage device after passing through the filter chamber; and a controller for acquiring dispersion state parameter information of the liquid cooling medium in the filter chamber, and adjusting the flow ratio in the first branch and the second branch according to the dispersion state parameter information, and / or adjusting the power of the dispersion functional module; wherein the sum of the flow ratios in the first branch and the second branch is 100%.

[0008] A liquid cooling system includes the above-described liquid cooling medium dispersion device.

[0009] A liquid cooling medium dispersion method includes the following steps: acquiring dispersion state parameter information of the liquid cooling medium in the filter chamber; determining the mode of the liquid cooling medium dispersion device based on the dispersion state parameter information, the mode including normal dispersion mode, enhanced dispersion mode, and self-cleaning mode; when the liquid cooling medium dispersion device is in enhanced dispersion mode, increasing the flow ratio in the second branch and / or increasing the power of the dispersion function module; when the liquid cooling medium dispersion device is in self-cleaning mode, keeping the flow ratio in the second branch unchanged and increasing the power of the dispersion function module until the liquid cooling medium dispersion device is in normal dispersion mode.

[0010] The liquid cooling medium dispersion device provided by this invention has the following advantages: First, the liquid cooling medium in the storage device is transported to the immersion chamber via the inlet pipe, and the liquid cooling medium in the immersion chamber is transported back to the storage device via the outlet pipe, thus realizing the liquid cooling cycle of the entire liquid cooling medium dispersion device. The inlet pipe includes a first branch and a second branch, with the dispersion chamber connected to the second branch. After the liquid cooling medium in the storage device flows into the inlet pipe, it enters the first and second branches respectively. The liquid cooling medium in the first branch flows directly into the immersion chamber, while the liquid cooling medium in the second branch flows into the immersion chamber after passing through the dispersion chamber. The dispersion component has two functions: one is to disperse the liquid cooling medium in the second branch, and the other is to disperse and filter the liquid cooling medium flowing out of the immersion chamber. Second, by setting a dispersion component between the storage device and the immersion chamber of the electronic device... The component, the dispersion component, includes a dispersion chamber, a dispersion functional module, and a filter chamber. The dispersion chamber and filter chamber are components for the flow of liquid cooling medium. The dispersion chamber disperses the liquid cooling medium in the storage device and then transports it to the immersion chamber. The filter chamber disperses and filters the liquid cooling medium in the immersion chamber and then transports it back to the storage device. The dispersion functional module in the dispersion component can disperse the liquid cooling medium flowing into and out of the immersion chamber. On the one hand, it reduces particle agglomerates flowing into the immersion chamber, ensuring the cooling efficiency of the liquid cooling medium. On the other hand, it disperses the liquid cooling medium flowing out of the immersion chamber and filters out particle agglomerates to prevent them from entering the storage device. At the same time, it can also dynamically adjust the flow rate ratio in the second branch and / or the power of the dispersion functional module based on the dispersion state parameter information of the liquid cooling medium in the filter chamber.

[0011] Furthermore, the liquid cooling medium dispersion device also includes a controller. The controller determines whether the liquid cooling medium in the immersion chamber exhibits agglomeration that affects normal cooling function by acquiring dispersion state parameters of the liquid cooling medium in the filter chamber. Based on these parameters, the controller selects one of two operations: First, it increases the flow rate in the second branch, allowing more liquid cooling medium to enter for dispersion, thereby reducing the flow rate in the first branch and minimizing the proportion of undispersed liquid cooling medium entering the immersion chamber directly. Second, it increases the power of the dispersion module, enhancing its processing capacity to more quickly disperse the liquid cooling medium in the second branch, further reducing the probability of agglomeration. Either operation can be selected, or both can be performed simultaneously. When both operations are performed, an adjustment ratio can be set. Alternatively, one method can be adjusted first, and the improvement in the dispersion state parameters of the liquid cooling medium in the filter chamber observed before selecting the other method. The actual adjustment process can be chosen according to specific needs.

[0012] The liquid cooling medium dispersion device provided by the present invention divides the liquid cooling medium in the inlet pipe into two streams that enter the immersion chamber. It eliminates the need to disperse all the liquid cooling medium. Instead, it selects the flow rate ratio entering the second branch as needed, that is, it divides the flow according to the dispersion state parameter information of the liquid cooling medium. This avoids the energy waste caused by continuous dispersion of the full flow, saves energy, and reduces costs.

[0013] In one embodiment, the dispersion state detection component includes a first pressure sensor and a second pressure sensor, which are respectively disposed on the inlet side and the outlet side of the filter chamber to obtain the pressure on the inlet side and the outlet side of the filter chamber. Both the first pressure sensor and the second pressure sensor are connected to a controller. The controller is used to calculate the inlet-outlet pressure difference in the filter chamber based on the pressure on the inlet side and the outlet side of the filter chamber. The controller is also used to adjust the flow ratio in the first branch and the second branch based on the inlet-outlet pressure difference, and / or adjust the power of the dispersion function module. The above setup, by installing a first pressure sensor and a second pressure sensor on the inlet and outlet sides of the filter chamber respectively, detects changes in the pressure difference between the inlet and outlet of the filter chamber. Based on the basic principles of fluid mechanics, as the blockage of the filter chamber worsens, the pressure difference between the inlet and outlet of the filter chamber will increase. By setting a pressure difference threshold and comparing the pressure difference between the inlet and outlet of the filter chamber with the threshold, the flow rate ratio in the second branch or the power of the distributed functional module can be adjusted according to the actual situation. Until the pressure difference between the inlet and outlet of the filter chamber is less than a certain threshold, the controller determines that the liquid cooling medium in the filter chamber is flowing smoothly and there are few particle agglomerates. Through the detection of the first and second pressure sensors, the operation is convenient, the cost is low, the accuracy is high, and the control is convenient.

[0014] The liquid cooling system provided in this application is equipped with the aforementioned liquid cooling medium dispersion device. Since the liquid cooling medium dispersion device has the aforementioned technical effects, the liquid cooling system equipped with the liquid cooling medium dispersion device should also have the corresponding technical effects.

[0015] The liquid cooling medium dispersion method provided by this invention has the following advantages: by acquiring the dispersion state parameter information of the liquid cooling medium in the filter chamber, the dispersion state of the liquid cooling medium in the immersion chamber is determined using the dispersion state parameter information of the liquid cooling medium in the filter chamber, thereby determining the working mode of the liquid cooling medium dispersion device at this time; when the liquid cooling medium dispersion device is in the normal dispersion mode, it can operate according to the initial set parameters; when the liquid cooling medium dispersion device is in the enhanced dispersion mode, it indicates that there are more particle agglomerates in the liquid cooling medium, at which time the flow rate ratio in the second branch can be increased, and / or the power of the dispersion function module can be increased to improve the dispersion degree of the liquid cooling medium in the filter chamber; when the liquid cooling medium dispersion device is in the self-cleaning mode, it indicates that the fluidity of the liquid cooling medium in the immersion chamber is poor, then the power of the dispersion function module needs to be increased until the liquid cooling medium dispersion device returns to the normal dispersion mode, ensuring the normal use of the device.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In this implementation, please refer to Figure 1 The liquid cooling medium dispersion device 1 includes: a dispersion assembly 11, comprising a dispersion chamber 111, a dispersion functional module 112, and a filter chamber 113, wherein the dispersion chamber 111 and the filter chamber 113 are isolated from each other, and the dispersion functional module 112 is used to disperse the liquid cooling medium in the dispersion chamber 111 and the filter chamber 113; and an inlet pipe 12, comprising a first branch 121 and a second branch 122, wherein the first branch 121 is used to supply the liquid cooling medium in the liquid storage device 2 into the immersion chamber 3 of the electronic device 4, and the second branch 122 is used to supply the liquid storage device... The liquid cooling medium in 2 flows into the immersion chamber 3 after passing through the dispersion chamber 111; the outlet pipe 13 is used to supply the liquid cooling medium in the immersion chamber 3 to flow back to the liquid storage device 2 after passing through the filter chamber 113; the controller 14 is used to acquire the dispersion state parameter information of the liquid cooling medium in the filter chamber 113, and adjust the flow ratio in the first branch 121 and the second branch 122 according to the dispersion state parameter information, and / or adjust the power of the dispersion function module 112; the sum of the flow ratios in the first branch 121 and the second branch 122 is 100%.

[0030] Specifically, the liquid cooling medium dispersion device 1 can be applied in electronic devices 4, such as immersion servers. The liquid cooling medium can be a nanofluid medium or a medium such as mineral oil or fluorinated liquid. Any medium whose viscosity increases or may agglomerate during circulation is acceptable. For example, the liquid cooling medium can be a high-performance graphene fluorinated liquid nanofluid medium. The liquid cooling medium dispersion device 1 is isolated from and independent of the electronic devices 4, and is only connected to them through pipelines. While leveraging the advantages of the liquid cooling medium such as excellent thermal conductivity, temperature uniformity, and material compatibility, it solves the core problem of the easy agglomeration of high-performance graphene fluorinated liquid and other liquid cooling media, which leads to the degradation of heat dissipation performance. This makes it truly feasible for practical application in immersion liquid-cooled servers, and can further improve the heat dissipation performance of single-phase immersion liquid-cooled server systems to a new level.

[0031] Furthermore, the information on the dispersion state parameters of the liquid cooling medium is mainly used to characterize the dispersion state of the liquid cooling medium. For example, it can be parameters such as viscosity, particle agglomerate concentration, or flow rate of the liquid cooling medium. Any parameter that can characterize the fluid dispersion state of the liquid cooling medium is acceptable.

[0032] The liquid cooling medium dispersion device 1 uses an inlet pipe 12 to transport the liquid cooling medium from the storage device 2 to the immersion chamber 3, and an outlet pipe 13 to transport the liquid cooling medium from the immersion chamber 3 back to the storage device 2, thus realizing the liquid cooling cycle of the entire liquid cooling medium dispersion device 1. The inlet pipe 12 includes a first branch 121 and a second branch 122. The dispersion chamber 111 is connected to the second branch 122. After the liquid cooling medium from the storage device 2 flows into the inlet pipe 12, it is then further distributed into the storage chamber 3. The liquid cooling medium flows into the first branch 121 and the second branch 122. The liquid cooling medium in the first branch 121 flows directly into the immersion chamber 3, while the liquid cooling medium in the second branch 122 flows into the immersion chamber 3 after passing through the dispersion chamber 111. The dispersion component 11 has two functions: one is to disperse the liquid cooling medium in the second branch 122, and the other is to disperse and filter the liquid cooling medium flowing out of the immersion chamber 3. Specifically, the dispersion component 111 is installed between the water storage device and the immersion chamber 3 of the electronic device 4. 1. The dispersion component 11 includes a dispersion chamber 111, a dispersion functional module 112, and a filter chamber 113. The dispersion chamber 111 and the filter chamber 113 are components for the flow of liquid cooling medium. The dispersion chamber 111 disperses the liquid cooling medium in the liquid storage device 2 and then transports it to the immersion chamber 3. The filter chamber 113 disperses and filters the liquid cooling medium in the immersion chamber 3 and then transports it back to the liquid storage device 2. The dispersion functional module 112 in the dispersion component 11 can disperse the liquid cooling medium flowing into and out of the immersion chamber 3. On the one hand, it reduces the particle agglomerates flowing into the immersion chamber 3 and ensures the cooling efficiency of the liquid cooling medium. On the other hand, it disperses the liquid cooling medium flowing out of the immersion chamber 3 and filters the particle agglomerates to prevent them from entering the liquid storage device 2. At the same time, it can also dynamically adjust the flow rate ratio in the second branch 122 and / or the power of the dispersion functional module 112 by using the dispersion state parameter information of the liquid cooling medium in the filter chamber.

[0033] For further information, please refer to [link / reference]. Figure 4The liquid cooling medium dispersion device 1 also includes a controller 14. The controller 14 determines whether the liquid cooling medium in the immersion chamber 3 exhibits agglomeration that affects normal cooling function by acquiring dispersion state parameter information of the liquid cooling medium in the filter chamber 113. The controller 14 selects two operations based on the dispersion state parameter information of the liquid cooling medium in the filter chamber 113. The first operation is to increase the flow rate ratio in the second branch 122, that is, to allow more liquid cooling medium to enter the second branch 122 for dispersion treatment, thereby reducing the flow rate ratio in the first branch 121, thus reducing the proportion of undispersed liquid cooling medium directly entering the immersion chamber 3 from the source. For example, the second method is to increase the power of the dispersion function module 112, that is, to improve the processing capacity of the dispersion function module 112, which can more quickly disperse the liquid cooling medium in the second branch 122, thereby reducing the probability of the liquid cooling medium entering the immersion chamber 3 agglomerating. The above two operations can be performed individually or simultaneously. When both methods are operated, the adjustment ratio can be set. Of course, one method can be adjusted first, and the improvement of the dispersion state parameter information of the liquid cooling medium in the filter chamber 113 can be observed before selecting the other method to adjust. The actual adjustment process can be selected according to actual needs.

[0034] The liquid cooling medium dispersion device 1 provided by the present invention divides the liquid cooling medium in the inlet pipe 12 into two streams that enter the immersion chamber 3. It eliminates the need to disperse all the liquid cooling medium. Instead, it selects the flow rate ratio entering the second branch 122 as needed, that is, it divides the flow according to the dispersion state parameters of the liquid cooling medium. For example, it dynamically divides the flow according to the aggregation time characteristics of nanofluids, avoiding the energy waste caused by continuous dispersion of the full flow rate, saving energy and reducing costs. While giving full play to the advantages of the liquid cooling medium such as excellent thermal conductivity, temperature uniformity and material compatibility, it can also avoid the main defect of easy aggregation in practical applications.

[0035] In some embodiments, the dispersion module 112 includes at least one of a physical dispersion module and a chemical dispersion module. The physical dispersion module disperses the liquid cooling medium by physical means, such as jet impact or stirring. The chemical dispersion module disperses the liquid cooling medium by chemical means, such as adding dispersants or stabilizers, such as silicates, polyphosphates, stearates, etc.

[0036] In some embodiments, the physical dispersion module includes an ultrasonic transducer module 1121 and / or a high-pressure micro-jet module 1122. The ultrasonic transducer module 1121 and the high-pressure micro-jet module 1122 perform dispersion treatment through different means. The ultrasonic transducer module 1121 performs coarse dispersion of the liquid cooling medium, while the high-pressure micro-jet module 1122 performs fine dispersion of the liquid cooling medium. The simultaneous use of the ultrasonic transducer module 1121 and the high-pressure micro-jet module 1122 yields better results. The chemical dispersion module includes a dispersant injection module 1123 and / or a stabilizer injection module. The dispersant injection module 1123 can be a surfactant, and the stabilizer injection module can be an anionic or cationic stabilizer. The selection of dispersant and stabilizer can be determined according to actual needs and is not limited to the method given in this embodiment. As for the use of the dispersant injection module 1123 and the stabilizer injection module, for example, a structure such as an injection device can be used to achieve quantitative addition of dispersant or stabilizer.

[0037] In some implementation methods, please refer to Figure 2The dispersion module 112 includes at least one of a dual-frequency ultrasonic transducer module, a high-pressure micro-jet module 1122, and a dispersant injection module 1123. Specifically, between the dispersion chamber 111 and the filtration chamber 113, the dispersion module 112 comprises three functional sub-modules, each independent of the others and optional for upgrades and replacements. The low-frequency transducer in the dual-frequency ultrasonic transducer module provides typical 28kHz ultrasound, which generates high-speed micro-jet and shock waves through its transient cavitation fragmentation effect, directly physically breaking up micron-sized large particle agglomerates. The high-frequency transducer in the dual-frequency ultrasonic transducer module provides typical 1.2MHz ultrasound, which applies high-frequency shear force to nano-sized particle agglomerates through its steady-state cavitation fragmentation effect and acoustic flow effect, suppressing secondary agglomeration caused by van der Waals forces and promoting uniform particle distribution. Through the synergy of low and high frequencies, full coverage of particle agglomerate size from micron to nano-sized can be achieved, effectively reducing total power consumption and temperature rise. The high-pressure micro-jet module 1122 drives the medium through a micron-level channel to form a high-speed jet. Utilizing its powerful shearing force, impact, and turbulent cavitation effect, it further disperses nanoscale particle agglomerates into near-original particle sizes, forming a "coarse crushing + fine grinding" functional combination with the dual-frequency ultrasonic module. The dispersant injection module 1123 is used to inject dispersant into the dispersion chamber 111 or the filter chamber 113. The dispersant can form an adsorption layer on the surface of nanoparticles, such as polyelectrolytes and polymer chains. Through the dual effects of steric hindrance and electrostatic repulsion, it counteracts the van der Waals forces and electrostatic forces between particles, reducing the spontaneous agglomeration tendency caused by the high surface energy state of the fresh surface after crushing. Based on ultrasonic and micro-jet physical crushing, it achieves a "cluster breaking-cluster stabilization" closed loop, forming a triple synergistic effect with the former two. In practical applications, any one of the dual-frequency ultrasonic transducer module, the high-pressure micro-jet module 1122, and the dispersant injection module 1123 can be selected, or any combination of two can be used. The best solution is for all three to work together.

[0038] In some embodiments, the dispersion component 11 includes a dispersion housing 114, with a dispersion chamber 111, a dispersion functional module 112, and a filter chamber 113 all disposed inside the dispersion housing 114. The dispersion chamber 111 and the filter chamber 113 are located on opposite sides of the dispersion housing 114, and the dispersion functional module 112 is located between the dispersion chamber 111 and the filter chamber 113. The dispersion housing 114 provides a convenient layout for the dispersion chamber 111, the dispersion functional module 112, and the filter chamber 113, and provides good support for the dispersion functional module 112.

[0039] In some embodiments, the distributed functional module 112 is detachably installed inside the distributed housing 114. Specifically, each sub-module in the distributed functional module 112 can be detachably installed inside the distributed housing 114, which facilitates disassembly, maintenance, or upgrades.

[0040] In some implementation methods, please refer to Figure 3 It also includes a diversion valve 15, whose inlet is connected to the water inlet pipe 12, and whose outlets are two, connected to the first branch 121 and the second branch 122 respectively. The diversion valve 15 is used to deliver the liquid cooling medium in the liquid storage device 2 to the first branch 121 and the second branch 122 according to the installation target ratio. Specifically, since the aggregation of nanofluids takes a certain amount of time and does not form in a short period of time, constantly dispersing the full flow of liquid cooling medium would cause a lot of power waste and increased heat generation. For energy conservation purposes, a diversion valve 15 is installed here to divert the full flow of liquid cooling medium delivered by the liquid storage device 2. For example, according to the actual situation, only 20% of the flow medium is adjusted to enter the second branch 122, and then flows into the dispersion chamber 111 for processing. After processing, it enters the immersion chamber 3 for heat dissipation. The remaining liquid cooling medium directly enters the immersion chamber 3 for heat dissipation along the first branch 121. This ensures that the full flow medium is dispersed before the nanofluid agglomerates, and at the same time, it can minimize the power consumption and heat generation of the dispersion device, achieving a balance of energy efficiency.

[0041] In some embodiments, the diversion valve 15 includes a valve body 151, a valve core 152, and a transmission rod 153. The valve core 152 is mounted on the transmission rod 153, and the transmission rod 153 is mounted on the valve body 151. The transmission rod 153 is connected to a controller 14, which controls the movement of the transmission rod 153 to change the position of the valve core 152 on the valve body 151. Specifically, by driving the transmission rod 153 through the controller 14, automatic control and automatic adjustment can be achieved, improving the degree of automation and minimizing power consumption.

[0042] In some embodiments, the valve body 151 is provided with an input channel 1511, a first valve port 1512, a second valve port 1513, a first output channel 1514, and a second output channel 1515. The first output channel 1514 and the second output channel 1515 are respectively connected to the first branch 121 and the second branch 122. The first valve port 1512 is located between the input channel 1511 and the first output channel 1514, and the second valve port 1513 is located between the input channel 1511 and the second output channel 1515. The valve core 152 includes a first valve core 1521 and a second valve core 1522. 522, the first valve core 1521 is used to block or release the first valve port 1512, and the second valve core 1522 is used to block or release the second valve port 1513. The first valve core 1521 and the second valve core 1522 are both mounted on the transmission rod 153. The transmission rod 153 is used to drive the first valve core 1521 and the second valve core 1522 to move synchronously, so as to adjust the opening of the first valve port 1512 and the second valve port 1513 in opposite directions. That is, during the movement of the transmission rod 153, while increasing the opening of the first valve port 1512, the opening of the first valve port 1512 is decreased, and vice versa, which is convenient for control.

[0043] In one specific embodiment, the diversion valve 15 includes a valve body 151, a valve core 152, a transmission rod 153, an electric actuator 154, and a control circuit. The valve body 151 is the main body of the diversion valve 15, and has an internal channel and valve port. The valve core 152 is a key functional component of the diversion valve 15, and the opening degree and flow rate of the valve port can be adjusted by controlling the position of the valve core 152. The electric actuator 154 is a power device that drives the valve core 152 to move. It can receive control signals sent by the control circuit and convert them into mechanical motion. The control circuit can be connected to the controller 14, or the controller 14 can be the control circuit itself. The transmission rod 153 is connected to the valve core 152 and the electric actuator 154. The actuator 154 is the transmission carrier that drives the valve core 152 to move; the control circuit is the core part for controlling and regulating the diversion valve 15. It can set parameters according to actual needs and control the diversion valve 15 in real time. The control circuit of the diversion valve 15 has a preset initial diversion ratio parameter, and can adjust this parameter in real time based on received external feedback signals, such as the inlet and outlet pressure difference signal in the filter chamber 113, and convert it into a control signal to command the electric actuator 154 to move. The electric actuator 154 drives the valve core 152 to move according to the control signal, changing the opening degree of the valve ports corresponding to the two output channels, thereby realizing the regulation of the diversion flow of the two output channels; Figure 3 The example shown is a case where the current split ratio between the first output channel 1514 and the second output channel 1515 is approximately 20%:80%.

[0044] In some embodiments, the first valve core 1521 is disposed in the middle of the transmission rod 153, and the second valve core 1522 is disposed at the end of the transmission rod 153. The first valve port 1512 and the second valve port 1513 are respectively located on both sides of the input channel 1511. When the first valve core 1521 blocks the first valve port 1512, the second valve port 1513 is in the open state, and when the second valve core 1522 blocks the second valve port 1513, the first valve port 1512 is in the open state. That is to say, only one of the first valve core 1521 and the second valve core 1522 can block the corresponding valve port. The first valve core 1521 and the second valve core 1522 can divert 100% of the flow. The flow can be adjusted by changing the opening degree of the first valve port 1512 and the second valve port 1513. The extension direction of the first output channel 1514 is perpendicular to the extension direction of the second output channel 1515, which is beneficial to make full use of space and facilitates the installation of the first branch 121 and the second branch 122.

[0045] In some embodiments, the dispersion chamber 111 is the main working area for dispersing the liquid cooling medium, receiving several liquid cooling media after being diverted from the diversion valve 15 and dispersing them; the filter chamber 113 is the working area for filtering large particle agglomerates in the nanofluid, preventing the accumulation of large particle agglomerates in the liquid cooling medium and thus reducing the heat dissipation performance of the nanofluid; specifically, it also includes a dispersion state detection component 16, used to acquire dispersion state parameter information of the liquid cooling medium in the filter chamber 113. The dispersion state detection component 16 is disposed inside the filter chamber 113 and is connected to the controller 14; the dispersion state detection component 16 can improve detection accuracy and facilitate automatic control by the controller 14.

[0046] In some embodiments, the dispersion state detection component 16 includes a first pressure sensor 161 and a second pressure sensor 162. The first pressure sensor 161 and the second pressure sensor 162 are respectively disposed on the inlet side and the outlet side of the filter chamber 113 to obtain the pressure on the inlet side and the outlet side of the filter chamber 113, thereby determining the dispersion state parameter information of the liquid cooling medium in the filter chamber 113. The first pressure sensor 161 and the second pressure sensor 162 are both connected to the controller 14. The controller 14 is used to calculate the inlet and outlet pressure difference in the filter chamber 113 based on the pressure on the inlet side and the outlet side of the filter chamber 113. The controller 14 is also used to adjust the flow ratio in the first branch 121 and the second branch 122 based on the inlet and outlet pressure difference, and / or adjust the power of the dispersion function module 112. The above configuration, by setting a first pressure sensor 161 and a second pressure sensor 162 on the inlet and outlet sides of the filter chamber 113 respectively, detects changes in the inlet-outlet pressure difference of the filter chamber 113. According to the basic principles of fluid mechanics, as the blockage of the filter chamber 113 worsens, the inlet-outlet pressure difference of the filter chamber 113 will increase. By setting a pressure difference threshold and comparing the inlet-outlet pressure difference of the filter chamber 113 with the pressure difference threshold, the flow ratio in the second branch 122 or the power of the distributed function module 112 can be adjusted according to the actual situation. Until the inlet-outlet pressure difference of the filter chamber 113 is less than a certain threshold, the controller 14 determines that the liquid cooling medium in the filter chamber 113 is flowing smoothly and there are few particle agglomerates. The operation is convenient, low-cost, highly accurate, and easy to control through the detection of the first pressure sensor 161 and the second pressure sensor 162.

[0047] In some embodiments, the filter chamber 113 is provided with a filter component, such as a filter screen. A first pressure sensor 161 is disposed on the side of the filter component near the immersion chamber 3, and a second pressure sensor 162 is disposed on the side of the filter component near the liquid storage device 2. Specifically, by installing the first pressure sensor 161 and the second pressure sensor 162 on both sides of the filter component, the dispersion state of the liquid cooling medium can be determined by the pressure change, which is convenient to operate and has low cost.

[0048] In some embodiments, the dispersion state detection component 16 is a potential sensor detection component. The potential sensor detection component is used to acquire the potential value of the liquid cooling medium in the filter chamber 113 and send the potential value of the liquid cooling medium in the filter chamber 113 to the controller 14, thereby determining the dispersion state parameter information of the liquid cooling medium in the filter chamber 113. The controller 14 is also used to adjust the flow ratio in the first branch 121 and the second branch 122 according to the potential value of the liquid cooling medium in the filter chamber 113, and / or adjust the power of the dispersion function module 112. Furthermore, a Zeta potential sensor interface can be reserved to select and upgrade the Zeta potential sensor, and simultaneously monitor the dispersion state of nanoparticles more accurately at the microscopic level. Through the macro-micro synergy of the pressure sensor and the Zeta potential sensor, more accurate feedback closed-loop control can be achieved. Specifically, the Zeta potential sensor can acquire the Zeta potential value of the particle surface. The Zeta potential refers to the potential value of the hydrodynamic shear surface of microparticles, which is an indicator of the charge density on the particle surface. The larger the Zeta potential, the greater the charge repulsion between particles, and the less likely the particles are to agglomerate. Generally speaking, nanoparticles exhibit good dispersion stability when the absolute value of the zeta potential is >30mV; below this critical value, they begin to aggregate easily. The more dispersed the nanoparticles are, the less likely they are to clog.

[0049] In one embodiment, a pressure sensor is distributed on the inlet side and the outlet side of the filter chamber 113 to detect the pressure difference change inside the filter chamber 113. At the same time, Zeta potential sensor interfaces are reserved in both the dispersion chamber 111 and the filter chamber 113 for later optional upgrades. Simultaneously, the dispersion state of nanoparticles can be monitored more accurately at the microscopic level to achieve more precise feedback closed-loop control.

[0050] In some embodiments, the inlet and outlet of the water inlet pipe 12 are connected to the liquid storage device 2 and the immersion chamber 3, respectively, and the inlet and outlet of the water outlet pipe 13 are connected to the immersion chamber 3 and the liquid storage device 2, respectively; and the inlet and outlet of the water inlet pipe 12 and the inlet and outlet of the water outlet pipe 13 are both quick-release interfaces; with this configuration, the liquid cooling medium dispersion device 1 can be used as a detachable integrated component, with quick-release interfaces or quick-connect plugs at both ends, and can be used as an optional component of the immersion liquid-cooled electronic device 4. When needed, it can be disassembled through the original pipe and replaced with the liquid cooling medium dispersion device 1; when not needed, the original pipe can be used.

[0051] Furthermore, the liquid cooling medium dispersion device 1 can be equipped with a supporting body, on which the dispersion component 11, the inlet pipe 12, and the outlet pipe 13 are all installed. The supporting body can be a shell or a frame, and a metal supporting body can be selected for its high strength and long service life. Of course, the function of the supporting body can also be achieved through the structure of the dispersion shell 114, that is, the dispersion shell 114 plays the main supporting role, and the inlet pipe and the outlet pipe can be fixed to the dispersion shell 114, which is simpler and saves space. Specifically, the supporting body is provided with a first inlet, a first outlet, a second inlet, and a second outlet. The first inlet and the first outlet are the inlet and outlet of the inlet pipe 12. The first inlet and the second outlet are used to connect to the liquid storage device 2, and the first outlet and the second inlet are used to connect to the immersion chamber 3. The inlets of the first branch 121 and the second branch 122 are all connected to the first inlet, and the outlets of the first branch 121 and the second branch 122 are all connected to the first outlet. The second inlet and the second outlet are the inlet and outlet of the outlet pipe 13. The first inlet, the first outlet, the second inlet, and the second outlet are all quick-release interfaces.

[0052] The liquid cooling medium dispersion device 1 provided by this invention features a detachable and integrated external quick-connect design, an optional internal functional sub-module design, and a dispersion function design that combines the synergistic effects of acoustic, flow, and chemical fields. Combined with an automatic flow diversion energy-saving mechanism and a differential pressure feedback closed-loop control mechanism, it can significantly improve the system's heat dissipation performance while enabling flexible deployment and maintenance of the device itself. It is highly compatible with single-phase immersion liquid-cooled server systems based on nanofluids, such as graphene fluorinated liquid.

[0053] In addition to the liquid cooling medium dispersion device 1 described above, the present invention also provides a liquid cooling system.

[0054] In some embodiments, a liquid storage device 2 and an immersion chamber 3 are also included. The liquid storage device 2 includes a cooling tower 21 and an external medium distribution device. The external medium distribution device can be a CDU (Coolant Distribution Unit 22). The CDU is connected between the cooling tower 21 and the liquid cooling medium dispersion device 1. The liquid cooling medium dispersion device 1 is connected between the CDU and the immersion chamber 3. Specifically, the CDU and cooling tower 21 are connected via inlet and outlet water pipes. The submersible liquid-cooled electronic device 4 completely immerses its heating elements in the liquid cooling medium. The low-temperature liquid cooling medium pumped by the CDU is forced to circulate and complete heat exchange to remove heat. The submerged area can be called the submersible chamber 3, which includes a medium distribution pipe. The low-temperature liquid cooling medium that has completed heat exchange in the submersible chamber 3 becomes a high-temperature liquid cooling medium. After being collected by the medium distribution pipe, it flows back to the CDU. The CDU is the cooling distribution unit 22, which is mainly responsible for pumping low-temperature liquid cooling medium to the electronic device 4 and exchanging heat between the high-temperature liquid cooling medium returning from the electronic device 4 and the low-temperature water flowing from the cooling tower 21, so that the high-temperature liquid cooling medium is cooled back to low-temperature liquid cooling medium. The cooling tower 21 is mainly responsible for pumping low-temperature liquid cooling medium to the CDU, assisting it in completing the re-cooling of the high-temperature liquid cooling medium, and exchanging heat between the high-temperature liquid cooling medium returning from the CDU and the atmosphere, so as to achieve the final discharge of heat.

[0055] This liquid cooling system is suitable for immersion liquid cooling systems using nanofluids, represented by graphene fluorinated liquid, as the medium. A detachable and integrated nanofluid liquid cooling medium dispersion device 1 is added between the CDU and the immersion chamber 3, and is connected to the inlet and outlet pipes of the immersion chamber 3 and the inlet and outlet pipes of the CDU through quick-connect couplings.

[0056] In addition to the liquid-cooled medium dispersion device 1 mentioned above, please refer to Figure 5 The present invention also provides a method for dispersing a liquid cooling medium. This method includes the following steps.

[0057] Step S1: Obtain the dispersion state parameter information of the liquid cooling medium in the filter chamber 113, and determine the mode of the liquid cooling medium dispersion device 1 based on the dispersion state parameter information. The modes include normal dispersion mode, enhanced dispersion mode and self-cleaning mode.

[0058] Step S2: When the liquid cooling medium dispersion device 1 is in enhanced dispersion mode, the flow rate ratio in the second branch 122 is increased, and / or the power of the dispersion function module 112 is increased.

[0059] Step S3: When the liquid cooling medium dispersion device 1 is in self-cleaning mode, the flow ratio in the second branch 122 remains unchanged, and the power of the dispersion function module 112 is increased until the liquid cooling medium dispersion device 1 is in normal dispersion mode.

[0060] This liquid cooling medium dispersion method obtains the dispersion state parameters of the liquid cooling medium in the filter chamber 113, and uses this information to determine the dispersion state of the liquid cooling medium in the immersion chamber 3, thereby determining the operating mode of the liquid cooling medium dispersion device 1. When the liquid cooling medium dispersion device 1 is in the normal dispersion mode, it can operate according to the initial set parameters. When the liquid cooling medium dispersion device 1 is in the enhanced dispersion mode, it indicates that there are more particle agglomerates in the liquid cooling medium. In this case, the flow rate ratio in the second branch 122 can be increased, and / or the power of the dispersion function module 112 can be increased to further disperse the liquid cooling medium in the filter chamber 113. When the liquid cooling medium dispersion device 1 is in the self-cleaning mode, it indicates that the fluidity of the liquid cooling medium in the immersion chamber 3 is poor. In this case, the power of the dispersion function module 112 needs to be increased until the liquid cooling medium dispersion device 1 returns to the normal dispersion mode to ensure the normal use of the device.

[0061] In some implementations, the dispersed state parameter information includes the inlet and outlet pressure difference within the filter chamber 113; please refer to Figure 6 The steps to determine the mode of the liquid cooling medium dispersion device 1 based on the dispersion state parameter information include the following steps.

[0062] Step S11: When the inlet and outlet pressure difference Δp1≤Δp<Δp2, it is determined that the mode of the liquid cooling medium dispersion device 1 is the enhanced dispersion mode, where Δp1<Δp2.

[0063] Step S12: When the inlet and outlet pressure difference Δp ≥ Δp2, it is determined that the liquid cooling medium dispersion device 1 is in self-cleaning mode.

[0064] Specifically, a first pressure sensor 161 and a second pressure sensor 162 are respectively installed on the inlet and outlet sides of the filter chamber 113. The first pressure sensor 161 and the second pressure sensor 162 are used to detect changes in pressure difference within the filter chamber 113. Assuming that the pressure detected by the first pressure sensor 161 at the inlet of the filter chamber 113 is p1, and the pressure detected by the second pressure sensor 162 at the outlet is p2, the pressure difference between the two is Δp = p1 - p2. According to the basic principles of fluid mechanics, Δp will increase as the blockage of the filter chamber 113 intensifies. The dispersion device of this invention initially sets two pressure difference thresholds Δp1 and Δp2, and the relationship between the two is Δp1 < Δp2. The specific values ​​can be adjusted and set according to the actual situation. When Δp < Δp1, it is determined that the medium in the filter chamber 113 is flowing smoothly and there are few particle agglomerates, and the dispersion device will operate in normal dispersion mode. When Δp increases until Δp1 < Δp < Δp2, it is determined that the dispersion effect of the dispersion device is currently poor. For example, there is already a certain concentration of particle agglomerates in the filter chamber 113. At this time, the dispersion device will start the enhanced dispersion mode, including increasing the proportion of diversion valve 15 to the branch of dispersion chamber 111, increasing the working power of the dual-frequency ultrasonic transducer, and increasing the high-pressure micro-jet module 112. 2. Drive pressure, increase dispersant injection amount / concentration in dispersant injection module 1123, etc., until Δp decreases to Δp<Δp1. At this time, the dispersion device will exit the enhanced dispersion mode and return to the normal dispersion mode. When Δp>Δp2, it is determined that the filter chamber 113 is close to the filtration limit after a long period of filter material accumulation. At this time, the dispersion device will start the self-cleaning mode of the filter chamber 113. The dual-frequency ultrasonic transducer, high-pressure micro-jet module 1122, and dispersant injection module 1123 will act on the filter chamber 113 with a certain intensity until Δp decreases to Δp<Δp1. At this time, the dispersion device will exit the self-cleaning mode of the filter chamber 113 and return to the normal dispersion mode.

[0065] In some embodiments, the method further includes: Step S13: When the inlet / outlet pressure difference Δp < Δp1, the liquid cooling medium dispersion device 1 is determined to be in normal dispersion mode; when the liquid cooling medium dispersion device 1 is in normal dispersion mode, the flow rate ratio in the second branch 122 and / or the power of the dispersion function module 112 are dynamically adjusted according to the inlet / outlet pressure difference. The above settings are to achieve dynamic balance, so that even in normal dispersion mode, the flow rate ratio in the second branch 122 and / or the power of the dispersion function module 112 are dynamically adjusted according to the change in the inlet / outlet pressure difference Δp, thereby maximizing energy savings.

[0066] For details, please refer to Figure 7The method of dynamically adjusting the flow ratio in the second branch 122 and the power of the distributed function module 112 based on the inlet and outlet pressure difference includes: Step S131: Setting the target inlet and outlet pressure difference Δp0; Step S132: Obtaining the inlet and outlet pressure difference Δp, and when the inlet and outlet pressure difference Δp > Δp0, increasing the flow ratio in the second branch 122 by a preset ratio, and after maintaining this for a first preset time, determining whether the inlet and outlet pressure difference Δp is less than or equal to Δp0; if not, increasing the power of the distributed function module 112 by a preset power range; In the above setting, when the inlet and outlet pressure difference Δp > Δp0, the flow valve is first adjusted to increase the flow ratio in the second branch 122. If the requirement cannot be met by simply changing the flow ratio in the second branch 122, the power of the distributed function module 112 will be increased; Since the flow valve is easier to control and has a lower cost, it can make fuller use of the power balance and reduce energy consumption in normal distributed mode.

[0067] In some implementations, the initial flow rate ratio of the second branch 122 is set based on the aggregation rate constant of the liquid cooling medium, the circulation flow rate of the liquid storage device 2, the target dispersion state parameter information, and the processing efficiency of the liquid cooling medium dispersion device 1. Specifically, in practical implementation, the dispersion device diverts the full flow of medium delivered from the CDU through the diversion valve 15. For example, depending on the actual situation, only the flow rate ratio of the medium in the second branch 122 is adjusted to 20%. After dispersion processing, the medium enters the server immersion chamber 3 for heat dissipation, while the remaining flow of medium directly enters the server immersion chamber 3 for heat dissipation along the first branch 121. The larger the aggregation rate constant of the liquid cooling medium, the larger the circulation flow rate of the liquid storage device 2, the smaller the target dispersion state parameter information, and the higher the processing efficiency of the liquid cooling medium dispersion device 1, the higher the initial flow rate ratio of the second branch 122.

[0068] The liquid cooling medium dispersion method provided by this invention, through the above-mentioned feedback closed-loop control mechanism, can automatically adjust the working mode and intensity in real time according to the actual situation, achieving maximum energy efficiency balance while ensuring dispersion effect, reducing heat generation, and enabling self-cleaning of the device, thus extending its service life. By embedding a detachable integrated dispersion device between the CDU and the immersion chamber 3, the acoustic field, flow field, and chemical field are integrated for coordinated dispersion, effectively solving the problem of liquid cooling medium agglomeration. Addressing the key point of energy efficiency balance, a diversion valve 15 is designed to dynamically adjust the dispersion processing flow rate, and combined with pressure sensor feedback control of dispersion intensity, greatly reducing power consumption while preventing over-processing and under-processing. To address the maintenance difficulties in industrial scenarios, an overall detachable integrated design is adopted, with independent selection of internal functional sub-modules, and self-cleaning control via pressure sensor feedback, achieving efficient maintenance of the dispersion device.

[0069] The liquid-cooled medium dispersion device 1 and method provided by the present invention, through the overall detachable structure, integrates internal functional sub-modules that can be independently selected and configured, realizing "plug and play" efficient deployment and maintenance, using a diversion mechanism to solve the energy consumption paradox of nanofluid processing, achieving nanoscale stable dispersion through the synergy of three physical and chemical fields, and dynamically optimizing the working mode with an intelligent feedback system, ultimately solving the core problem of nanofluid particle agglomeration while maintaining high thermal conductivity; including the following beneficial effects.

[0070] (1) Detachable integrated design: The whole device is a detachable module, connected in series in the medium circuit between CDU and server immersion chamber 3 via quick connectors. When the distributed function is not needed, the original pipeline can be replaced. The whole machine can be quickly disassembled and reassembled during maintenance, supporting flexible replacement.

[0071] (2) Intelligent diversion energy-saving mechanism: An adjustable diversion valve 15 is installed at the inlet, which diverts only part of the medium into the dispersion device, while the undiverted medium flows directly into the immersion chamber 3. Based on the aggregation time characteristics of nanofluids, dynamic diversion is achieved to avoid energy waste caused by continuous full-flow processing and to realize energy efficiency optimization.

[0072] (3) Three-field synergistic dispersion technology: The dual-frequency ultrasonic module and the micro-jet module form a physical crushing combination of "coarse crushing + fine grinding" for the nanofluid aggregated particles. The dispersant injection module 1123 provides a chemical adsorption layer to reduce the tendency of spontaneous particle aggregation. The three work together to achieve a closed loop of "physical agglomeration + chemical stabilization".

[0073] (4) Differential pressure feedback closed-loop control: The dual pressure sensors of the filter chamber 113 monitor the differential pressure Δp in real time. The dispersion device dynamically switches different working modes according to the magnitude of Δp. The working modes are divided into normal dispersion mode, enhanced dispersion mode and self-cleaning mode.

[0074] (5) Modular and scalable architecture: three major functional sub-modules. Independent design, supporting optional upgrades as needed.

[0075] (6) Macro-micro collaborative monitoring: The standard configuration includes a differential pressure sensor for macro-state monitoring, and a reserved Zeta potential sensor interface. With optional upgrades, it can simultaneously perform micro-state monitoring. Dual-dimensional collaborative monitoring supports precise feedback closed-loop control.

Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
